Description

Technical Field

[0001] The invention relates to the technical field of veterinary instruments, and in particular to a mouse fixing platform for implanting a mouse scalp expander. Background Art

[0002] Mice belong to the order Rodentia. Laboratory mice are derived from wild house mice. They have been used for comparative anatomical research and animal experiments since the 17th century. Currently, more than 500 independent outbred groups, inbred lines and mutant lines have been bred. They are the most thoroughly studied mammalian experimental animals in the world today. The body length of an adult mouse is generally 9.0-12.5cm. They are currently widely used in medical research such as safety and toxicity experiments, drug screening, oncology, immunology and genetic diseases. Mouse scalp expander implantation is an experimental surgical technique. The scalp expander is an expandable silicone device that is surgically implanted under the mouse scalp, and then liquid is gradually injected into the expander to gradually expand the scalp tissue. The purpose is to simulate the process of human scalp tissue expansion and to study the biological changes after tissue expansion, such as tissue regeneration, angiogenesis, cell proliferation, etc.

[0003] When performing scalp expander implantation experiments on mice, they will resist violently, so they need to be fixed to ensure the stability of the experiment. However, the fixed mice may keep twisting their heads due to stimulation, making it difficult for veterinarians to perform surgery on their scalp. Therefore, we proposed a mouse fixation table for mouse scalp expander implantation. Summary of the invention

When the arc-shaped pressing piece 305 moves downward, it drives the top rectangular long plate 306, the inner arc-shaped air cushion 309 and the oblique abutment plates 310 on both sides to move downward together. When the rectangular long plate 306 moves downward, the extension spring 307 is compressed. When the arc-shaped air cushion 309 moves downward, it bends inward together with the arc-shaped pressing piece 305. When the arc-shaped air cushion 309 moves down to contact with the mouse, the neck of the mouse is elastically pressed and fixed. After the arc-shaped pressing piece 305 drives the inner arc-shaped air cushion 309 to move downward to contact with the neck of the mouse, it is pulled by the tension rope 304 and drives the inner arc-shaped air cushion 309 to bend inward together and fit with the neck of the mouse. The mouse neck is adapted to be pressed and fixed by setting a deformable arc-shaped pressing piece 305. When the arc-shaped pressing piece 305 moves downward, it drives the oblique abutment plates 310 on both sides to move downward together. The oblique abutment plates 310 contact the mouse before the arc-shaped pressing piece 305 and squeeze it. After the mouse scalp surgery is completed, the servo motor 302 drives the linkage rod 303 to reverse. When the linkage rod 303 reverses, the rolled-up tension rope 304 is unwound. At this time, the arc-shaped pressing piece 305 and the top rectangular long plate 306 lose tension. The extension spring 307 that loses pressure pushes the rectangular long plate 306 upward through the extension force. When the rectangular long plate 306 moves upward, it drives the arc-shaped pressing piece 305 at the bottom to move upward to the initial position and restore to the initial shape. The arc-shaped pressing piece 305 is pushed upward and reset by the extension force of the extension spring 307. After the mouse's neck is fixed, its body is stuffed between the two arc-shaped pressing plates 404 in the square empty shell 401. The electric push rod 403 pushes the arc-shaped pressing plate 404 obliquely toward the inner side of the square empty shell 401. When the arc-shaped pressing plate 404 moves, it pushes the mouse obliquely and fixes it. When the arc-shaped pressing plate 404 moves obliquely, it drives the vertical baffle plate 406 at the bottom to move inward together. When the two vertical baffle plates 406 move inward, they block and limit the two sides of the mouse to reduce the mouse's range of movement. By respectively opening a ventilation circular hole 1 405 and a ventilation circular hole 2 407 on the surface of the arc-shaped pressing plate 404 and the surface of the vertical baffle plate 406, it is convenient for the mouse to ventilate and dissipate heat.When the mouse is continuously pushed by the arc-shaped pressure plate 404 and the vertical baffle plate 406, it will gradually form a lying posture. When the mouse continues to lie down, its feet will be extended outward and inserted between the return springs 408 with a large number of turns. The bottom of the return spring 408 is in contact with the top of the square platform 1 at all times. As the vertical baffle plate 406 moves inward, it will move downward with the oblique push of the arc-shaped pressure plate 404. The vertical baffle plate 406 drives the return spring 408 to move inward while compressing the return spring 408, so that the return spring 408 gradually bends when moving inward. When the return spring 408 bends, it will clamp the inserted foot. By arranging a return spring 408 with a large number of turns at the bottom of the vertical baffle plate 406, the extended foot of the mouse is clamped. When the mouse is stuffed into the square empty shell 401, the mouse's tail is placed on the long round rod 503 through the round through hole 402, and the retraction spring 506 drives the square pressure plate 507 to the long round rod through the retraction force When the square pressing plate 507 moves in the direction of the mouse 503, the plastic rubber pad 509 at the bottom moves together when the square pressing plate 507 moves downward. When the plastic rubber pad 509 moves downward, the mouse tail on the long round rod 503 is pressed and fixed. Then, the driving motor 502 is started to drive the long round rod 503 to rotate. When the long round rod 503 rotates, the mouse tail fixed on the surface is rolled up. The mouse tail is rolled up and fixed by rotating the long round rod 503. By setting a plastic rubber pad 509 of elastic material at the bottom of the square pressing plate 507, the mouse tail can be rolled up and fixed. The rubber pad 509 tightly presses the mouse tail, and at the same time, the push spring 511 inside the second concave plate 510 pushes the sleeve push plate 512 to push the plastic rubber pad 509 through the extension force. The push spring 511 pushes the sleeve push plate 512 to push tightly from both sides of the plastic rubber pad 509. The elastically connected plastic rubber pad 509 is limited in sliding by arranging a short through rod 508 on the long round rod 503 to penetrate the square pressure plate 507 and the first concave plate 505.
